Lead arsenate poisoning was diagnosed in 2 beef heifers and was suspected in 6 other cattle from the same herd that had died previously and were not examined. Clinical signs in affected cattle included staggering, dehydration, hemorrhage, acidemia, and shock. Diagnosis was by arsenic and lead analysis of urine samples and kidney and liver tissue digests. Both examined heifers died within 4 days of onset of clinical signs. These cattle had been moved from an area with poor grazing conditions to a pasture with abundant forage. This pasture had an open shed that contained an open sack of lead arsenate insecticide. Old stores of this inorganic insecticide may still exist on farms or ranches, and are a hazard to livestock.
在2头小母牛中诊断出砷酸铅中毒，在同一牛群中另外6头先前死亡且未进行检查的牛中怀疑有砷酸铅中毒。患病牛的临床症状包括蹒跚、脱水、出血、酸血症和休克。通过对尿液样本以及肾脏和肝脏组织消化物进行砷和铅分析来进行诊断。两头接受检查的小母牛在出现临床症状后4天内死亡。这些牛从放牧条件差的地区转移到了牧草丰富的牧场。这个牧场有一个开放式棚屋，里面有一袋打开的砷酸铅杀虫剂。这种无机杀虫剂的旧库存可能仍存在于农场或牧场中，对牲畜构成危害。
